I'd be aligned with Mr. Strom that way, in terms of offering an opinion in an area that's not my expertise.
However, I will strongly point out that we've talked about both the very strong level of capital investment in airframes and engines that produce the lowest level of noise possible and the greatest amount of efficiency. Therefore, on anything from a tax perspective, I'd also hope that it would be offset by looking at the level of investment that an airline is making.
